Melitta user here. I have been for many, many years. I use the #6 filter cones. The bad thing about being the ONLY #6 user in the state is that I have bought all of the filters for sale within 20 miles of me an no one carries them any more. That said - I took delivery of a FULL CASE of 40ct boxes of filters yesterday from the Jungle Site. That's a happy feeling to have enough filters for a year and not having to drive all over the countryside to find them. There was that one tragic week in 2020 where I had to resort to using paper towels for filters. Savage.
He's explaining in detail each aspect as he goes. You don't need to learn from scratch each time, you just get your process down and reproduce. Coffee is a spectacularly complex substance so you can go really deep. If you just drink it for caffeine, you do you. Don't hate on someone who cares.
Convoluted? Dude's pouring water. If that's convoluted to you, you're just a dumb person. If _pouring water_ is 'trying hard' to you, you're also a lazy person.
